<p>A product fluidising apparatus comprising a chamber having at least one product inlet controlled by a first valve and adapted to receive a product supply, at least one gas inlet controlled by a second valve and adapted to receive a pressurised gas supply, and at least one product outlet which is connectable to a pressurisable product delivery pipe and which is controlled by a third valve. The first, second and third valves are provided with actuators capable of cycling each valve from a substantially open position to a substantially closed position. And, the apparatus includes a controller capable of controlling and cycling the operation of each valve in sequence, in such a manner that while the first valve is substantially open the second and third valves are substantially closed, and while the first valve is substantially closed the second and third valves are substantially open.</p> |
